An IRI Specification defining addresses for referencing WebSphere MQ queues and topics in a way similar to URL Web addresses.

A WSDL Binding Specification defining extensions for WSDL that describe WebSphere MQ applications, including its connections, the queues or topics it uses, its message exchange pattern (request-response or one-way) and the quality of service and message formats it uses.

WebSphere MQ Service Definitions can be created for applications that use either SOAP or native (non-SOAP) messages.

These specifications enables developers to write WebSphere MQ Service Definitions that can help catalogue your applications in a standard, machine-readable way, and use the Service Definitions to aid the development, management and monitoring of WebSphere MQ applications, particularly where tools exist that take advantage of these specifications.
